Vishay Nobel P9420 Series of Pressure Transmitters Provides Range Up to 15,000 psi (0 - 1,000 bar) and Secondary-Containment Option Up to 22,500 psi

Combined error due to non-linearity, hysteresis, and repeatability is better than 0.25% FSO, while stability is better than 0.1% FSO per year

MALVERN, PENNSYLVANIA — March 30, 2005 — Vishay Intertechnology, Inc. (NYSE: VSH) announces the availability of Vishay Nobel P9420-800 series pressure transmitters. A further development in the range of hammer-lug union fittings for the offshore oil industry, the P9420-800 series pressure transmitters are an extension of the P9420 series with fused ceramic sensors that provide high shock and vibration immunity.

All ranges of these transmitters are built within a male sub-casing, offering optional secondary containment of pressure up to the proof rating of the union assembly. The P9420-800 transmitters are available with a two-year warranty, and wide variety of connector options to suit the application requirement. Construction is of ultra-rugged stainless steel.

These transmitters range up to 15,000 psi (0 - 1,000 bar) and the secondary-containment option is up to 22,500 psi. Combined error, non-linearity, hysteresis, and repeatability accuracy is better than 0.25% FSO, while stability is better than 0.1% FSO per year. Output is 4-mA to 20-mA, two-wire.

The transmitters have ATEX and are also tested to IEC 68 Test Ea100g/6ms, 3 axes and Test Fc 10-800Hz, 5g, 3 axes for shock and vibration. They conform to IP68 BS5490:1977 and IEC 529:1976 and are tested to IEC 801-3 Parts 2,3,4 and 6 EN 50082-2 for RFI/EMC immunity.
